It all started when Gray said Keane has struggled to adapt in his current role as the Republic of Ireland assistant manager as the players are unable to play to the same standard as he did when he was a player.

McAteer offered Keys a way out when he said he initially didn’t see why Keane was receiving a great deal of praise but changed his mind after playing in centre midfield alongside him for Ireland.

Gray echoed McAteer’s views but Keys didn’t back down from his original point.

And many took to Twitter to disagree with Keys including former United defender Rio Ferdinand who posted “Riiiiiiiiiiiichard” along with emojis reflecting his embarrassment of the subject.

Ferdinand played alongside Keane at Old Trafford for over three years

There were even some rival fans who mocked keys with one Twitter user saying: “I’m a Man City fan and even I’ll admit Roy Keane was a great player. I can’t wait until he [Keane] sees this video.”

Another user added: “He [Keys] misses the point. Roy Keane’s game was all about winning the ball, tackling, motivating his team-mates and never saying die.

“He was probably one of the finest players ever in that role and world class at it.”

Below you can see the full debate on whether Keane was a great player or not.
